Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interior decoration production, in particular to a material loading and transferring mechanism of a full-automatic suspension conveyor chain for conveying materials. Background Art

[0002] Suspended conveyor chains, also known as catenaries, consist of chains, rails, hangers, brackets, drive seats, and adjustment seats. They are highly efficient conveying systems that have been widely used in automotive interior production technology in recent years. Their operating principle is that a motor drives the chain in a circular motion to transport items. The advantage is that items do not come into contact with any obstacles during their transport, preventing them from being damaged or affected. This type of conveyor line can also accommodate multiple stops and transport items in multiple directions, meeting diverse logistics needs. However, traditional catenaries require multiple loading and unloading ports at various locations, resulting in a large footprint and the need for dedicated personnel to transport materials to these ports, increasing labor costs. To reduce production costs, existing systems have developed devices that connect catenaries to AGVs (automated guided vehicles). These devices leverage internet technology to solve the problem of automated material loading and unloading, saving labor and reducing production costs. However, in practice, material handling equipment can wobble while traveling on the catenary, and errors can easily occur when docking with the AGV at the loading and unloading points, causing loading and unloading failures and even line stoppages.

[0003] The invention with application number CN202211060242.0 discloses a catenary system loading and unloading transfer docking mechanism, which includes two symmetrically arranged transverse closing devices, the transverse closing device including a correction cylinder, a base and a transverse slide; the upper end of the transverse slide is provided with a longitudinal sliding device, the longitudinal sliding device including a longitudinal slide and a propulsion cylinder; the upper end of the longitudinal slide is provided with a lifting device, the lifting device including a jacking cylinder, a lifting slider and a material pallet. This invention solves the docking error of the upper and lower materials through the transverse correction of the transverse closing device and the longitudinal correction and positioning of the positioning device; when the material tooling is running on the catenary and shaking, the bracket with the product tooling can also be quickly corrected and positioned, effectively solving the problem that the current catenary system is prone to docking errors when docking with the AGV cart at the loading and unloading docking point. However, the invention adopts two symmetrically arranged horizontal closing devices and longitudinal sliding devices, and its structure is complex, and the lifting device adopts a lifting cylinder, a lifting slider and a material pallet. Such a structure has limited load capacity and is only suitable for lightweight products, and its operation is unstable. In addition, according to the application method of the catenary system loading and unloading transfer docking mechanism described in the invention specification, it can be seen that the invention requires manual activation of the correction cylinder, positioning cylinder, lifting cylinder, and propulsion cylinder in sequence. Therefore, the operation is complicated, there are many operating steps, the production efficiency is low, and there are safety risks. Utility Model Content
